SPECIFICATION forming part of Letters Patent No. 481,952, datedSeptember 6, 1892.

Application filed March 12, 1892. Serial No. 424,667. (No model.)

To all whom it may concern:

Be it known that I, FREDERICK F. INGRAM, a citizen of the United States,residing at- Detroit, county of Wayne, State of Michigan, have inventeda certain new and useful Improvement in Molds; andldeclare the followingto be a full, clear, and exact description of the invention, such aswill enable others skilled in the art to which it appertains to make anduse the same, reference being had to the accompanying drawings, whichform a part of this specification.

My invention relates to the construction of molds for casting a bodyprovided with a se ries of receptacles or cells; and it consists of thedevices and appliances, their construction, combination, andarrangement, hereinafter specified and claimed, and illustrated in thedrawings submitted herewith, in which- Figure 1 is a vertical section ofadevice embodying my invention, showing the jointed connection of thetwo parts D D in elevation. Fig. 2 is a horizontal section on the linea: so, Fig. 1. Fig. 3 is a view of the atomizer-casting in verticalsection. Fig. 4 is a view of the same in horizontal section.

The objectof my invention is to construct an article provided with aseries of cells in an integral casting in a simple, economical,

and eflicient manner.

In order to the better understanding of the nature of the device to beformed by means of the mold, I have shown in Figs. 3 and 4am articleprovided with a series of cells all constructed in an integral castingby means of my improved mold embodied herein, in which- A represents abody or case formed with a series of cells a, separated from one anotherby partition-Walls a and having a common outer wall a and inner wall aThe said article is also formed with a hollow chamber A in the center,the said chamber-being covered at the top, as shown at A Theconstruction of the mold is carried out as follows: B represents thebase of the mold, provided with a series of cores B to form the cells a,the cores having passages 1) between one another to form thepartition-walls a of the cells. These cores B may have a stationaryengagement with the base B.

0 represents a central vertically-movable core located within the lineof the cores B, which may conveniently be arranged in a circle upon thebase B. The central coreis separated from thecores B, so as to provide apassage therebetween, as at O, for the flow of the metal to form theinner wall a of the cells. This core 0 may be made vertically movable byany suitable means, as by a screw C having a threaded engagement in thebase B.

D denotes an inclosing mold -case constructed in two parts D D jointedlyconnected, as shown at d. This case when in place surrounds the cores Band is spaced therefrom, as shown at d, to form the outer wall a of thecells. The two parts D D of the case are provided each with a coverportion D separated from the top of the core 0, as shown at c, to formthe top A, covering the chamber A. The hinged parts D D may be securedtogether in operation in any suitable and wellknown manner. Thus theymay be formed with flanges d united by a screw (Z The cover portions Dare constructed with an orifice, as at 01 through which the metal may bepoured, a funnel D being employed in connection therewith. The core 0preferably has a detachable engagement with the screw 0 as shown at 0The upper ends of the cores Bare preferably constructed with reducedextremities, as shown at 1), whereby the cells a are formed with acorresponding neck.

The operation of the device is as follows: The case D being closed aboutthe cores in a proper manner, the metal is poured into the mold,after'which the two parts D D of the case are opened. The central core 0is then raised by means of the screw 0 carrying therewith the articlecast in the mold, the said article being thus lifted oif from the coresB. W hen said article is clear from the cores B, the central core 0 maybe lifted off from the screw 0 when the said core 0 may also be removedfrom the casting. The screw 0 is then run down, the core 0 dropped intoplace, and the case D closed and fastened, when the mold is ready forarepetition of the operation.

What I claim as my invention is- 1. In a mold, the combination of thebase B,

the cores B thereupon, a central verticallymovable core, and aninclosing case, substantially as described.

2. In a mold, the combination of the base B, cores B, central movablecore G, screw 0 having a threaded engagement with the base and carryingsaid movable core, and an inclosing case, said core having a detachableengagement with said screw, substantially as described. 10

In testimony whereof I sign this specification in the presence of twowitnesses.
